Andy, many thanks for this. There seem to be a number of versions of the E772. I have instructions for a Type 6, which seems to be 20.000 Ohms/Volt on DC, 10,000 AC. But the one I have is marked with a plate 10,000 Ohms AC and DC, and I guess that is the case with your's, so thanks, I now have the appropriate instructions. I have found some probes, and it does seem to be working, at least on DC volts.
I am curious as to why there were versions some of which were far superior to others in terms of accuracy. It can't have cost much less to produce a 10,000 instrument. Do you think this was because they were made for different applications as per the Avo 7 and 8, or perhaps one model superceded the other?
